Technically New England opened as a small underdog in this matchup, but it took less than half-an-hour for markets to adjust and offer the Patriots at -2.5. The Patriots are traditionally a publicly backed team and the immediate 3.5 point swing appears to have been the right move, as that price has held firm at most betting shops.

When asked about the early action coming in on this game, Dave Mason of BetOnline shared that most bookies will be wearing blue and gold Sunday evening.

"We will be massive Rams fans on Super Bowl Sunday both straight up and ATS. 79% of the bettors are on the Pats -2.5 and 58% are on Pats to win outright. When it comes to the over/under, our bet count is split 50/50."

Aside from the initial movement, both the Super Bowl spread and moneyline have remained quite steady. It has been the over/under total where bettors have seen the most movement, and those that jumped on the under early should be feeling good about themselves right about now.

After opening at 58 points at many shops, this line now sits at 56.5 at most of the online sportsbooks monitored by Sportsbook Review. Their grid of 30+ sites offering Super Bowl betting odds shows a range of over/under offerings anywhere between 56 and 58, with only two books still offering the line at 58. A range this varied does mean that bettors looking to place a wager on this particular option is smart to shop around first, as those two extra points could be the difference between a win and a loss.

Prop Betting Takes Center Stage

Super Bowl prop betting has become more popular than the commercials and has given casual fans literally hundreds of ways to cash in off of the year's biggest sporting event. A diehard Maroon 5 fan who has little to no knowledge of the game can bet on singer Adam Levine's outfit selection or which song he will perform first, and those simply looking to give America's newest trend a go can bet on who the Super Bowl MVP thanks first in his post-game interview (we like God at +190).

"The game going to OT is going to be its annual sweat with 95% of bettors on Yes. The same can be said for a Safety with 96% on Yes. Both opened at +850 and have been bet down to +800." shared Mason.

"As always, the coin toss is getting a ton of bets, with 55% of bettors on Heads."

When asked about the most bet prop up to this point, he offered that "the National Anthem is the prop getting the highest bet count, with action split 50/50 on the over/under."

Drew Gilroy, linesmaker at Sportsbook Review, gave us a look at the action he was seeing in terms of prop betting markets.

"We are seeing large numbers of wagers being placed on the Gronkowski yards prop, with the public liking Gronk to get over 54.5 yards in the Super Bowl (-115). Another popular bet our players like is Aaron Donald to record a sack before Tom Brady throws an interception (-130)."
